Flight Director Royce Renfrew discusses the early end to the spacewalk on January 15, 2016 which included NASA astronaut Tim Kopra and ESA (European Space Agency) astronaut Tim Peake.

The pair ended its spacewalk at 12:31 p.m. EST with the repressurization of the U.S. Quest airlock following an early termination after Kopra reported a small water bubble had formed inside his helmet.

Commander Scott Kelly assisted the crew members with an expedited removal of their spacesuits and helmets. Once they removed the spacesuits and helmets, the astronauts used a syringe to take a water sample and retrieve the helmet absorption pad to determine how much water was introduced. Engineers are already looking at data to find what may have prompted the water to form inside Kopra's helmet.

The crew was never in any danger and returned to the airlock in an orderly fashion. The astronauts replaced a failed voltage regulator that caused a loss of power to one of the station's eight power channels last November, accomplishing the major objective for this spacewalk.

The 4 hour and 43 minutes spacewalk was the third for Kopra and the first for Peake, who both arrived to the station Dec. 15. It was the 192 in support of assembly and maintenance of the orbiting laboratory.
